The invention discloses an urban power grid anti-catastrophe capability assessment method and a related device, and the method comprises the steps: building a complete assessment index system, carrying out the hierarchical distribution of first-level indexes and second-level indexes, carrying out the expert scoring for different levels and different indexes, paying attention to the direct impact degree of each index on other indexes, and, on the basis, calculating a judgment matrix, an average matrix and a weight vector related to each level of index; and finally, calculating a total evaluation result according to the two-stage weight vectors. The evaluation result obtained by comprehensive calculation under the influence of each index is more accurate and more accords with the description of the actual power grid anti-catastrophe capability. The technical problem that in the prior art, detailed evaluation analysis is not carried out on a single index, so that the evaluation result of the power grid anti-catastrophe capability is lack of accuracy and reliability can be solved.
Description
technical field [0001] The present application relates to the technical field of power grid evaluation, in particular to a method and related devices for evaluating the anti-disaster capability of urban power grids. Background technique [0002] With the rapid development of the national economy and the rapid advancement of urbanization, the system security and power supply reliability requirements of urban power grids are also continuously increasing. In recent years, long-term and large-scale power outages caused by natural disasters and other reasons have caused serious social impacts and huge economic losses. Therefore, the research on the comprehensive evaluation of the power supply reliability of the urban power grid has been valued by many electric power scholars and experts. However, most of the current research focuses on the comprehensive operation and failure risk assessment of the power grid. There is a lack of research on the evaluation of the urban power grid'...
